The Guide

Acceptable use
Please don't:
- Use the Guide during an official exam, or in any way that breaks a competition's rules.
- Try to break, overload or get around the security of the site, or access other people's data.
- Scrape or copy the site in a way that harms it or breaks the license below.

Content and license
Unless marked otherwise, the Guide's lessons, problems, simulations and code are licensed under CC BY-NC-SA 4.0. You may share and adapt them for non-commercial purposes if you credit the USAPhO Guide (usapho.one) and release your adaptations under the same license.
Past exam problems are cited and linked rather than copied, and they belong to their original publishers. Names such as F=ma, USAPhO and AAPT, and any other trademarks, belong to their owners.
Your contributions
When you submit a lesson, problem, simulation or fix (through the editor or a pull request), you confirm that you wrote it or have the right to share it, and you license it under CC BY-NC-SA 4.0 like the rest of the Guide. Contributions are reviewed and may be edited, combined or removed. Your GitHub username and commits are public and may be credited on the contributors page.
Community
Our Discord server is run on Discord, so Discord's terms apply there, along with the server's own rules. Be respectful and keep it about physics.
No guarantees
We work hard to get things right, but the Guide is written by students and volunteers and may contain mistakes, including wrong answers. It is provided “as is”, without warranties of any kind, and is not a replacement for official exam materials or a teacher. Using it does not guarantee any exam score or award. If you find an error, please report it.
Limitation of liability
To the extent the law allows, the people who run and contribute to the Guide are not liable for any indirect or consequential damages, or for any loss arising from your use of the site. The Guide is free, and our total liability for any claim is limited to zero dollars.
Changes and ending
We may change or stop the Guide, or update these terms, at any time. If the terms change, we will update the date at the top. Continuing to use the site after that means you accept the new terms.
Law
These terms are governed by the laws of the State of California, USA.
